Much to their surprise, scientists are finding dozens of black holes deep within densely packed collections of stars called globular clusters. We spoke to three astrophysicists—Rainer Spurzem, Carl Rodriguez and Jay Strayder—who are using a record-breaking computer simulation, and other methods, to learn the clusters’ secrets, including whether they gave rise to recently observed ripples in space-time.
